Kerry Says Iran War ‘Never Should Have Happened’

Former Secretary of State John Kerry discusses the conflict between the US and Iran and ongoing negotiations between Washington and Tehran to reach a deal. "It is going to be exceedingly difficult to get the Iranians to give up more than they had in a prior agreement," Kerry tells Bloomberg Television. He adds the Obama-era deal, the Joint Comprehensive Plan of Action (JCPOA) was "the strongest" nuclear agreement in history.
